so that doors don’t fly open if there is more pressure inside than outside; designed to stay closed so that the air pressure doesn’t change how hard or easy it is for the doors to stay open
name 4 components of a doorway to consider with regards to accessibility.
- direction of swing
- force to open door
- width clearance
- threshold (door saddle)
